FRANK DENTLER, OF PARKVILLE, MICHIGAN.

W H E E L SPECIFICATION forming part of Letters Patent N0. 435,581,dated September 2, 1890.

Application filed May 17, 1890- Serial N0. 352,120- (No model.)

To all whom, it may concern.-

Be it known that I, FRANK DENTLER, a citizen of the United States,residing at Parkville,in the county of St. Joseph and State of Michigan,have invented a new and useful Wheel, of which the following is aspecification.

This invention has relation to improvements in wheels, the objects inview being to provide an extremely rigid light wheel and one not liableto buckle or dish, and this without sacrifice to the strength of thewheel or without in any way adding to its weight.

WVith the above objects in view the invention consists in certainfeatures of construction hereinafter specified, and particularly pointedout in the claims.

Referring to the drawings, Figure 1 is a side elevation of a wheelconstructed in accordance with my invention. Fig. 2 is a centralvertical section. Fig. 3 is a detail of the central portion of one ofthe spokes. Fig. 4 is a detail of one of the trusses.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 designates the hub provided with the usual bands, and at each side ofits center with an annular series of sockets or mortises 2, arranged ata suitable distance apart. These mortises or sockets may be located at agreater or less distance apart, at the option of the builder, and inaccordance with the proposed use of the wheel.

3 represents the rim, which is of the usual construction, and isencircled by the usual tire 4, and provided upon its inner peripherywith the outer spoke sockets or mortises 5.

The spokes 6 of the wheel, of which there may be any number, are splitor bifurcated from their inner ends to any point beyond the same,forming the opposite bifurcations or branches 7, each of whichterminates in a tenon 8, adapted to enter a mortise of each of theannular series formed in the hub. In this instance the bifurcationsextend to near the center of the spokes, and in order to prevent themfrom further splitting a rivet may be passed through the bifurcations,or, as herein shown, a metallic ring may be driven snugly upon the same.

9 represents the metallic ring, and to fur ther aid in its retention Iinsert through the same and into the bifurcations a screw or rivet 10.

A wheel thus constructed, it will be observed, is extremely strong andrigid, for the reason that each of the spokes is thoroughly braced ateach side of the center of the hub, and any dishing or buckling of thewheel is almost impossible. The bifurcations, it will be observed, areeach one-half the thickness of the spoke, and therefore do not add anyweight over an ordinary solid spoke.

In order to brace the bifurcations and strengthen the same throughouttheir lengths and thus enable me to employ extremely light spokes, shorttruss-rods are wedged between the same near their inner extremities orat the fork of the spoke. 11 designates the aforesaid truss-rods, andthe same maybe of wood or metal, leather, the. In this instance I formthem of leather and pass through them meta-l pins 12, terminating attheir ends in points 13 for taking into the spokes.

Having thus described my invention, what I claim is 1. Theherein-described wheel, the same consisting of the hub provided at eachside of its center with the circumferential series of sockets 2, the rim8, having sockets 4, the spokes 6, bifurcated at their longitudinalcenters from their inner ends to about their middles, said bifurcationsterminating in tenons 8, fitting the sockets 2, and the outerendsterminating in tenons fitting the sockets of the rim, and the trusses11, wedged between the bifurcations, and each provided with a metal pin12, passed longitudinally therethrough and terminating beyond the endsof the trusses in points 13, entering the bifurcations, substantially asspecified.

2. The herein-described wheel, the same consisting of the hub providedat each side of its center with the circumferential series of sockets 2,the rim 3, having sockets 4, the spokes 6, bifurcated at theirlongitudinal centers from their inner ends to about their middlcs, saidbifurcations terminating in tenons 8, fitting the sockets 2, and theouter ends terminating in tenons fitting the sockets of the rim, thetrusses 11,wedged between the bifurcations, and each provided with ametal pin 12, passed longitudinally there- In testimony that I claim theforegoing as through and terminating beyond the ends of my own I havehereto atfixed my signature in IO the trusses in points 13, entering thebifu'rpresence of two Witnesses.
